Determined to keep that from happening again, the Dallas Police Department is proposing the city tighten its regulations prohibiting camping on public property. Monday morning Assistant Chief Tom Lawrence will walk the council through the PowerPoint below, which says Section 32.1 of the Dallas City Code -- the section prohibiting "overnight camping" on public park property without a permit -- provides only "limited regulation of camping on city owned/controlled property." Which is how the city wound up being occupied, says the briefing.

The events of 2011 taught city and police officials a great many things, says the briefing, among them: "Enforcement tools to manage camping are limited." And: "An atmosphere for increased crime can be created." And: "Interference with use and enjoyment of property by the public is diminished."

The briefing calls for a complete overhaul of the ordinance. The proposal very clearly states where camping is prohibited (Dallas City Hall and outside the convention center, for starters), and defines what a "temporary shelter" is ("a tent or other portable or impermanent structure in or under which a person can be sheltered from the elements"). The rewrite also "provides a defense where express city authorization/permit is obtained," says the briefing, which means a "person will be given one hour to remove the temporary shelter and any other personal property." After that, says the document, "City will remove and handle remaining property using existing police department and city policies."

The briefing, which was posted Friday night to the city's website, is below.
